In an atom, the nucleus contains protons and neutrons. Protons are positively charged (+1) and neutrons are neutral (as the name suggests) and therefore have no charge.
In the Periodic Table, the proton number is shown with the Atomic Mass of an element.
Going around the outside of the nucleus are electronsthanks to electromagnetic force. Electrons are negatively charged (-1).
An atom has an equal amount of protons and electrons to make the overall charge zero. When there are fewer electrons, the atom becomes a positive ion, and when there are additional electrons the atom becomes a negative ion.
Electrons are arranged in 'rings' called electron shells. The first shell (closest around the nucleus) can only have two electrons to fill it up. The other shells can have up to eight. The more shells between the nucleus of an atom and the outer shell the easier it is for the atom to lose electrons through bonding to others. This is because the forces are weaker than if there were only a couple of shells.
Uh... I hope that answered your question.
What else can I help you with?
Is there any force acting on an electron?
The answer simply depends on the environment that the electron is in. If the electron is in orbit around the nucleus of an atom then there will be a strong electromagnetic force acting on the electron towards the nucleus.
What does the nucleus of one atom want to do to the electrons of a nearby atom?
If the nucleus is missing an atom, it will try to steel an electron from another atom.
In every atom are the electrons surrounded by a positively charged nucleus?
Yes, in an atom, electrons are negatively charged particles that orbit around a positively charged nucleus composed of protons and neutrons. The nucleus is held together by strong nuclear forces, while the electrons are attracted to the nucleus by electromagnetic forces.
The center solid part of the atom?
The center solid part of an atom is called the nucleus. It contains protons and neutrons, which are held together by strong nuclear forces. The nucleus makes up most of the atom's mass and is surrounded by a cloud of electrons.
Is nucleus smaller than atom?
An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
Which of the universal forces act only on protons and neutrons in the nucleus of an atom?
The strong nuclear force acts only on neutrons and protons in the nucleus of an atom. The opposite would be a weak nuclear force.
Is there any force acting on an electron?
The answer simply depends on the environment that the electron is in. If the electron is in orbit around the nucleus of an atom then there will be a strong electromagnetic force acting on the electron towards the nucleus.
What are the four forces acting on the atom?
The four fundamental forces acting on atoms are gravity, electromagnetic force, weak nuclear force, and strong nuclear force. Gravity is responsible for attracting masses towards each other, electromagnetic force holds electrons in orbit around the nucleus, and weak and strong nuclear forces govern interactions within the atomic nucleus.
What describes the electric forces inside an atom?
Electric forces inside an atom are responsible for holding the nucleus together and attracting electrons to the nucleus. The positive charge of the protons in the nucleus creates an attraction for the negatively charged electrons, keeping them in orbit around the nucleus in specific energy levels. This balance of attractive forces governs the stability and structure of the atom.
What does the nucleus of one atom want to do to the electrons of a nearby atom?
If the nucleus is missing an atom, it will try to steel an electron from another atom.
Why electrostatic forces exist between nucleus and outermost electrons?
Electrostatic forces between the nucleus and outermost electrons exist due to the attraction between opposite charges. The nucleus carries a positive charge, while electrons carry a negative charge. This attraction keeps the electrons in orbit around the nucleus, creating stability within the atom.
What is name of the force that holds the nucleus of an atom together?
intermolecular forces
What forces hold an atom's nucleus together?
The primary forces that hold an atom's nucleus together are the strong nuclear force, which is attractive and overcomes the electrostatic repulsion between positively charged protons, and the weak nuclear force, which is responsible for certain types of radioactive decay. These forces play a critical role in maintaining the stability of the atom's nucleus.
How are electrons bound to the nucleus in an atom?
Electrons are bound to the nucleus in an atom through electromagnetic forces. The negatively charged electrons are attracted to the positively charged protons in the nucleus, creating a stable orbit around the nucleus.
Which particle has the greatest chance of overcoming the electrostatic forces surrounding the nucleus of an atom?
An electron has the greatest chance of overcoming the electrostatic forces surrounding the nucleus of an atom. This is because electrons are much lighter and can be easily influenced by external forces, allowing them to move around the nucleus within the electron cloud.
Is an example of the electrostatic force acting in an atom?
An example of the electrostatic force acting in an atom is the attraction between the positively charged nucleus and the negatively charged electrons. This force keeps the electrons orbiting around the nucleus in stable energy levels, maintaining the atom's overall neutral charge.
In every atom are the electrons surrounded by a positively charged nucleus?
Yes, in an atom, electrons are negatively charged particles that orbit around a positively charged nucleus composed of protons and neutrons. The nucleus is held together by strong nuclear forces, while the electrons are attracted to the nucleus by electromagnetic forces.
